Headings questions are designed to test your ability to understand the main idea presented in each paragraph. The instructions for the question can be phrased like this or like this. In both cases, you are required to match a heading to the main message of a paragraph. In order to get the mark, you have to write a Roman numeral on the answer sheet. A common error with headings style questions is when candidates match a heading that only covers part of the main idea of the paragraph. Remember you are looking to match the main message.
